Adding the dependency and enabling web endpoints (using for instance endpoints.default.web.enabled) is all that’s required. +``` +- Security Upgrade - https://github.com/spring-projects/spring-boot/wiki/Spring-Boot-2.0.0-M4-Release-Notes#security +``` +Another important change is that there is no longer a separate security auto-configuration for the Actuator:(management.security.enabled) no longer exists and web endpoints are disabled by default (endpoints.default.web.enabled) to prevent exposing sensitive information by default. The sensitive flag of each endpoint is also gone to make things more explicit in the security configuration. To restore the previous behaviour: + +Enable Actuator web endpoints: endpoints.default.web.enabled=true in your configuration + +Create or adapt your security configuration to secure endpoints with the role of your choice (see the Security section below) + +M5 +Management Server-related properties have been moved from management.* to management.server.*. We also fixed the meaning of management.server.context-path: it is now the endpoint management equivalent of server.context-path (only active when management.server.port is set). Additionally, you can also set the base path for the management endpoints with a new, separate property: management.endpoints.web.base-path. + +For example, if you’ve set management.server.context-path=/management and management.endpoints.web.base-path=/application, you’ll be able to reach the health endpoint at the following path: /management/application/health. + +M6 +After some feedback from the community, the default management.endpoints.web.base-path has been changed from "/application" to "/actuator" to avoid collision with user-defined mappings (see #10970). + +The endpoints. keys have moved to management.endpoints. + + +RC1 +Spring Security default user +We’ve restored the ability to auto-configure a single user via configuration keys. These can be found at spring.security.user. +``` +- OAuth 2.0 Support +Functionality from the Spring Security OAuth project is being migrated to core Spring Security. OAuth 2.0 client support has already been added and additional features will be migrated in due course. +``` +If you depend on Spring Security OAuth features that have not yet been migrated you will need to add org.springframework.security.oauth:spring-security-oauth2 and configure things manually. If you only need OAuth 2.0 client support you can use the auto-configuration provided by Spring Boot 2.0. We’re also continuing to support Spring Boot 1.5 so older applications can continue to use that until an upgrade path is provided. +``` + +- Jackson serialization + +``` +The default value for spring.jackson.serialization.write-dates-as-timestamps is now set to false, meaning all JSR310 date types will be serialized as ISO-8601 strings instead of array-like types. + +RC1 + +Jackson +SerializationFeature.WRITE_DATES_AS_TIMESTAMPS is now disabled by default. + +Date conversion +It is possible to control the date format for date types from well-known packages (java.util, org.joda.time and java.time) using a single property. +``` + +- Renamed + +``` +========================== +CONDITION EVALUATION DELTA +========================== + +``` + +### Spring Cloud + +https://github.com/spring-projects/spring-cloud/wiki/Spring-Cloud-Finchley-Release-Notes + +- Remove the Zipkin Stream server +https://github.com/spring-cloud/spring-cloud-sleuth/issues/727 +- All of Feign code from Spring Cloud Netflix has been moved to a new project, Spring Cloud OpenFeign +- spring-cloud-starter-eureka is deprecated.
